NBA rankings: Grizzlies fall out of Top 5

We're ranking the top five and bottom five NBA teams through the rest of the regular season. The Grizzlies have fallen out of our "Top 5" list, replaced by the Golden State Warriors. Those two teams play Friday night at FedExForum.

Top 5

1. San Antonio (38-11): The Spurs extended their winning streak to 10 last week, despite losing Manu Ginobili Wednesday and Tim Duncan Saturday to injuries. This week, they're faced with their annual Rodeo Trip, which features a nine-game road trip beginning Wednesday at Minnesota while the rodeo takes over the AT&T Center.

2. Oklahoma City (35-12): It was a bizarre week for Thunder guard Russell Westbrook. First, he had one of his annual temper tantrums in the midst of the Thunder's blowout win over Memphis. Then, in a matchup of All-Star guards Saturday, Westbrook was completely outplayed by Cleveland's Kyrie Irving as the Cavaliers pulled off the upset.

3. Miami (30-14): Despite losing to Boston and Indiana, the Heat managed to hang on to the top spot in the East with wins over Brooklyn and Toronto. Miami has won six of its last eight, but at some point must show it is capable of beating the Pacers, Chicago and New York, teams the Heat are winless against this season.

4. Denver (30-18): The Nuggets took advantage of a home-heavy schedule in January to jump into the playoff picture. Not only are the Nuggets 20-3 at home this season, but they are riding a six-game winning streak, second only to the Spurs among active streaks. But after Tuesday and Thursday's home games against Milwaukee and Chicago, Denver goes on the road for a four-game trip out East.

5. Golden State (30-17): This week will tell if the Warriors deserve to be in the top five. They've won four in a row against the likes of Toronto, Cleveland, Dallas and Phoenix. Now the Warriors hit the road for games at Houston, Oklahoma City, Memphis and Dallas.

Bottom 5

1. Orlando (14-33): With nine consecutive losses, the Magic is one away from tying their longest losing streak of the season. And the way they're playing, they might catch the Bobcats, who earlier had an 18-game slide.

2. Charlotte (11-35): The Bobcats began their five-game road trip with losses at Chicago, San Antonio and Houston. The trip concludes this week with losses, er stops, at Miami and Cleveland before returning home Friday to face the Los Angeles Lakers.

3. Sacramento (17-32): The Kings have lost three straight and eight of 10 heading into consecutive games against Utah.

4. New Orleans (15-33): Just when it looked like the Hornets were going to turn things around with a win at Memphis, they go and lose four in a row to end their road trip 1-4. The return home to face Phoenix before heading back on the road for three more games.

5. Washington (11-35): For a moment, the Wizards were looking like a respectable team after the return of guard John Wall. Now they've dropped four straight and are looking like the same old Wizards. At Memphis Friday, they scored 30 in the first quarter and 46 in the final three.
